AMINO ALCOHOL SOLUTIONS OF N-(N-BUTYL)THIOPHOSPHORIC TRIAMIDE (NBPT) AND UREA FERTILIZERS USING SUCH SOLUTIONS AS UREASE INHIBITORS

摘要

A method of producing reduced volatility of urea fertilizers comprising: dissolving N-(n-butyl)-thiophosphoric triamide (NBPT) in an amino alcohol having the formula 1 (H)xN((CH2)mOH)n where m is 1-3, x is 0 or 1, and n is 2 when x is 1 and 3 when x is 0: or the formula 2 (H)yN((CH2)CHOHCH3)z such that the length of the carbon chain where the secondary hydroxyl group is located is 3, y is 0 or 1, and z is 2 when y is 1 and 3 when y is 0 to form an NBPT solution; and combining a urea fertilizer in granular or liquid form with the NBPT solution.
